Peak Brightness

In its brightest mode (aptly named "Brightest") the Viewsonic PJD5123 achieves a brightness of 433 cd/m2, which is as bright as the brightest LCD TVs. When Eco was turned on, the level was still a respectable 375 cd/m2, so you shouldn't worry about ambient light washing out your presentation. Of course, if you want a mode with higher color fidelity, like Movie or our calibrated User 1, your brightness level will drop to less than a third of the projector's max.

Tunnel Contrast

Projectors have a problem with tunnel contrast: they shoot out a bunch of light, which scatters as it reaches its target. Consequently, they don't perform well on our tunnel contrast test, which measures the brightness of a shrinking, black box surrounded by white space. The smaller the dark box, the less protection it has against the scattering of the white border.

Uniformity

Many projectors also have problems emitting a projection that's of uniform brightness. The PJD5123 was not too bad, with its upper corners dimming by about 30% of the maximum brightness. On a flatly colored screen, one might notice a slight dimming along the top edge, but it would likely be invisible, given an image. The dimming of the top row and the brightness of the bottom center was retained over all modes.

Greyscale Gamma

The PJD5123's greyscale gamma is impressive. This chart measures its ability to transition smoothly between black and white. The slope should be smooth and even, between 2.1 and 2.2. The Viewsonic maintained a slope of 2.19, which is just perfect. Usually, not even TVs achieve such a smooth and well-weighted transition. This is one of the best we've ever seen.
